PYRITE SUN LARGE
A broken Pyrite Sun Large. This is a natural formation of Pyrite and something quite different to the usual more cubic looking varieties. Striations radiate out from the centre. Our Suns are hand selected at the source for their excellent quality. We are well known for our metals range and have pyrite specimens showing cubic, orbicular and octahedral crystals, as well as these suns. Pyrite (“fools gold”) is popular with all age groups. A great piece for the collector of unusual pieces. This Pyrite Sun comes with a perspex stand for display and looks even better in person. Unfortunately this one was broken in the post but it is very large and would still be good as a display specimen for the collection. Could be used for making jewellery.

Crystals, Galena, Metal Specimens, Minerals of the World, Pyrite, QuartzQUARTZ GALENA SPHALERITE CHALCOPYRITE
A beautiful mineral specimen featuring Quartz Galena Sphalerite Chalcopyrite crystals. Super cute and collectable, specimens like this are quite fascinating. When looked at under magnification you can really see the shape of each different mineral. I could look at these for hours, in fact I do. If you don’t have too much space left in your cabinet a piece like this covers several different mineral types. A great mineral specimen whether you are a beginner or advanced collector.
